           dataType: 'jsonp',
           type: "GET",
           url: "http://10.163.14.56:9000/customerservice/getDet?callback=?",
            cache: false,

            jsonp    : false,
               
           success: function (data) {
               alert("Success");
// what i have  to do here
           }
             
        });
